Castrating bands are used in the food industry for cattle and other ruminants in order to increase their weight and improve the taste of the meat (with the advantage of relevant economies of scale for the breeder). This is a relative painless measure compared to use of a Burdizzo tool or emasculators to crush the spermatic cords and disrupt the blood supply. Castrating bands can also be used on male animals in order to make them more tractable. These are quality rubber bands for castrating livestock. These castrating bands are in packs containing 100 castrating bands. You must have an applicator to apply castrating bands.
